Development of Voice Recognition Control Systems

Todd Whiteman and Michael Ostrego
Advisor: Dr. T. L. Stewart

Speech provides one of the most convenient and rapid channels of communication between man and machine. However, there are many barriers which inhibit wider applications of such communications. From a technological viewpoint, major obstacles to speech recognition come from problems related to speaker independence and continuous speech. This presentation discusses the proposed development of a control system using speech as the controlling input. It also examines various markets involving voice recognition systems, current problems involving voice recognition, and various approaches toward voice recognition. Early research indicates that current speech recognition control systems are costly and not readily available. For this reason, this project proposes to develop a system with a limited vocabulary and a projected recognition accuracy of around 90%. These constraints decrease cost and increase the portability. The system will be able to recognize a series of one word commands and have a relatively fast recognition time.
